REVOLVER.

SPECIFICATION forming part of Letters Patent No. 391,214, dated October16, 1888.

Application filed August 1, 1888.

To aZZ whom it may concern:

Be it known that I, REINHARD T. TORKEL- SON, of the city and county ofWorcester, and State of Massachusetts, have invented certain new anduseful Improvements in Revolvers; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, forming a part of thisspecification, and in which- Figurel representsa side view, partly insection, of so much of a revolver as is necessary to illustratemyimprovements. Fig. 2 is a view of the lower part of Fig. 1, showing myimproved cylinder stop and lock device, hereinafter described,disengaged from said cylinder in Fig. l, the various parts being shownin their normal positions with the cylinder locked. Fig. 3 is a rear endview of the cylinder and barrel-strap,showing how said cylinder is heldin position longitudinally by my improved device for that purpose, alsohereinafter described. Fig. at is a bottom view of the rear end of thebarrel-strap with my improvement applied thereto. Fig. 5 is a transversesection taken on line a, Fig. 1. Fig. 6 is a side view of the catch-postand upper part of the frame of my improved revolver. Fig. 7 is a centrallongitudinal section, upon an enlarged scale, taken on line b, Fig. 3.Figs. 8 and 9 are transverse sections,upon the same enlarged scale asFig. 7, taken at the points indicated by lines a (1, same figure; andFigs. 10 and 11 are detached perspective views, also upon an enlargedscale, of parts relating to my improved cylinder stop and lock devicepreviviously referred to.

My invention consists of improvements in the mechanism for stopping andlocking the cylinder against rotary motion at the end of each partialrevolution thereof, for holding said cylinder in position longitudinallyand for locking the barrel-strap to the catch-post,

- as hereinafter more fully set forth.

To enable those skilled in the art to which said invention appertains toobtain a full and clear understanding thereof, 1 will now proceed todescribe it more in detail.

In the drawings, A represents part of the Serial No. 281.680. (Nomodel.)

frame, B part of the barrel, 0 the barrel-strap, D the cylinder, E the.trigger, and F the trigger-guard, of the revolver.

My improved device for stopping and looking the cylinder against rotarymotion, as aforesaid, is connected with the trigger E, and 5 5 isconstructed in the following manner: stop-lever, e, is hinged near itsrear end, at f, to the upper end of said trigger, preferably in avertical slot formed therein. Said stop-lever is provided upon the topof its front end with an upwardly-turned flange, 6', adapted to engagewith the usual. peripheral notches, g, in the cylinder, and with asuitable spring, h, for forcing up said forward end, which in thisinstance is arranged between the top of its rear end and the frame A.The lever is also provided with ahook, e projecting downward from itsfront end, adapted to engage with a shoulder or notch, 13', on the frontend of the bolt 11, and is further, preferably, provided with a shoulderor notch, 6 adapted to bear against the frame or some stationary pointto control its upward movements. Said notch c is not essential, however,as the lever may be made to strike a stationary point at any convenientplace in front of its pivot to effect the same result, and I thereforedo not limit myself thereto.

The bolt t is fitted in a longitudinal opening in the trigger under thestop-lever e, and 8c in addition to the shoulder or notch 2" previouslyreferred to, which is formed on its forward end, it is provided with asuitable spring,

j, for exerting a forward pressure thereon, said spring in this instancebeing fitted in the bolt-opening and adapted to bear against the rearend of said bolt. The forward movements of the bolt are controlled byforming a slot therein to produce a shoulder, i", which bears against afixed transverse pin, It, in the trigger, and said bolt is forced backto disengage it from the hook e on lever e by making its forward endunder the notch i convex shaped, so as to act as a cam against the stationary point Z when the trigger is pulled 9 back, and thus produce theabove-described result.

As various well-known ways may be adopted for controlling the forwardmovements of the bolt, I do not limit myself to the construction shownand described.

The lever e is in this instance shown as being hinged to thetrigger-pivot; but I do not limit myself thereto.

The other features of my invention combine in one device means forholding the cylinder in position. longitudinally, as well as forlockingthe barrel-strap O to the catch-post A, and which device will now bedescribed. Said barrel-strap G is provided with the usual verticalopening to receive the catch-post A, and also with a transverse openingto receive the bolt m, and said bolt is in turn slotted vertically, asshown at n, to allow the catchpost to pass up through when the bolt isin position in the barrel-strap, and is also provided with a suitablespring, 0, for forcingsaid bolt at one side of its slot, into alongitudinal groove, on, formed in one side of the catch-post, andthereby fastening the barrel-strap to said catch-post. The spring 0 isin this instance arranged transversely in a slot or opening, 0, in thebolt. It is held in position between said bolt and a vertical screw, 0which, being passed up through said slot or opening in the bolt, servesto hold said bolt from being forced out of the strap by its spring. Thestrap is fastened to the catch-post by forcing the same down over saidcatch-post, as usual, the bolt being thereby forced to one side untilarriving opposite the groove m, when it is sprung into the same andsecurely held in position, said operation being facilitated by roundingthe inner edge of the bolt, as shown at of, so that it may readily slipover the top edge of the post, and by making the groove m in said postwith a square shoulder at its upper edge, as shown in Fig. 5, to holdthe strap as aforesaid.

Between the openings 0' and n in bolt m is formed a vertical transverseslot, p, which is also extended down through the barrel-strap (see Figs.7 and 9) to receive a centrally-pivoted lever, q. The vertical slot andsaid lever are arranged to come just back of the cylinder, and the leveris tilted to bring one or the other of its ends q below the barrelstrap,as shown in Figs. 3 and 9, to hold the cylinder by the operation of thebolt m, the lever being pivoted at g to the bolt, also made with itslower edge concave in shape, and a cen tral fixed bearing, 1-, arrangedunder the same to tilt it in first one direction and then the other bythe forward and back movements of said bolt against the same. In saidFig. 9 the bolt and lever are shown in their normal positions with oneof the ends q in position for holding the cylinder as aforesaid. \Vhenit is desired to remove said cylinder, the bolt is pushed in by pressingon the end m thereof to unlock the strap from the catch-post, and uponsaid strap being swung up said bolt is pushed in again part way to bringthe lever q into a horizontal position with both of its holding ends gabove the cylinder, thus admitting of said cylinder being readilywithdrawn from the spindle upon which it turns.

For the purpose of convenience in fitting the tilting-lever (1 inposition, I prefer in practiee to make the upper end thereof fork-.shaped to fit its pivot g and form the stationary bearing 7 by fittingand fastening a sepa' rate strip or plate in asuitable recess in theunder side of the barrel-strap, as is best shown in Figs. 4 and 7. I donot, however, limit myself thereto.

Having described my invention, what I claim therein as new, and desireto secure by Letters Patent, is

1 In a fire-arm, the combination of the cylinder D, having theperipheral notches g,with the lever c, hinged near its rear end to thetrigger, having the upturned flange 6 in front of its pivot adapted toengage with said cylinder-notches, and a suitable spring for forcing upits forward end, also having a downwardly-projecting hook, o at or nearits forward end, adapted to engage with a shoulder or notch, i, on thefront end of a bolt, '6, as well as means for controlling the upwardmovements of said forward end, said bolt 1' fitted in a longitudinalopening in the trigger under lever cand having a suitable spring forforcing it forward, also having a convex-shaped cam on its front endadapted to bear against a stationary point, Z, to force said bolt backwhen the trigger is pulled back, and means for controlling its forwardmovements, and trigger E, substantially as and for the purpose setforth.
